What best practices should be followed when naming variables in PHP scripts for better understanding?

When naming variables in PHP scripts, it is important to use descriptive and meaningful names to improve code readability and understandability. Variable names should be clear, concise, and reflect the purpose of the data they hold. Avoid using vague or generic names like $data or $temp. Instead, opt for specific names that indicate the content or use of the variable.

// Bad variable naming
$data = "Hello, World!";
$temp = 10;

// Good variable naming
$message = "Hello, World!";
$temperature = 10;
